Executes structured diagnostic runbooks when CloudWatch Anomaly Detection triggers alarms. Uses the AWS SDK CloudWatch client (GetMetricData, DescribeAlarms) to gather context and suggest remediations.
Parses Nginx error logs using configurable regex patterns and the GoAccess real-time log analyzer API. Clusters recurring 502/504 errors and correlates with upstream health check failures.
Diagnoses PostgreSQL slow queries using pg_stat_statements extension, EXPLAIN ANALYZE output parsing, and pg_stat_user_indexes for index usage analysis. Identifies missing indexes, sequential scan bottlenecks, and lock contention issues.
Triages AWS CloudWatch alarms using the CloudWatch DescribeAlarms API, GetMetricData for historical analysis, and CloudTrail LookupEvents for root cause correlation. Prioritizes alerts by blast radius and provides remediation playbooks.
Diagnoses CrashLoopBackOff pods using the Kubernetes API /api/v1/pods endpoint, kubectl logs --previous, and container runtime inspection via crictl. Identifies OOMKilled events, missing ConfigMaps, and image pull failures.
Automates Nginx error diagnosis using nginx -T configuration dump, error.log pattern matching, and the Nginx Plus REST API /api/8/http/upstreams endpoint. Resolves 502 Bad Gateway, SSL handshake failures, and upstream timeout issues.
Automates incident response for AWS CloudWatch alarms using boto3, the CloudWatch GetMetricData API, and AWS Systems Manager runbook documents. Maps alarm states to diagnostic procedures and remediation actions.
Analyzes PostgreSQL query execution plans using EXPLAIN (ANALYZE, BUFFERS, FORMAT JSON) and the pg_stat_statements extension. Identifies sequential scans, nested loop inefficiencies, and index recommendations for slow queries.
Executes structured incident response procedures for Kubernetes clusters using kubectl, kube-state-metrics, and the Kubernetes Events API. Automates pod crash diagnosis, OOMKill analysis, and node pressure triage.
Inspects Docker container health using the Docker Engine API v1.45 /containers/{id}/json and /containers/{id}/stats endpoints. Diagnoses OOM kills, restart loops, and network connectivity issues with automated log analysis via /containers/{id}/logs streaming.
Parses and diagnoses Nginx error logs and access logs using pattern matching against known error signatures. Integrates with the Nginx Plus REST API /api/8/ endpoints for real-time upstream health, connection metrics, and SSL certificate expiration monitoring.
Diagnoses Kubernetes pod failures using kubectl and the Kubernetes API server endpoints. Analyzes CrashLoopBackOff, OOMKilled, and ImagePullBackOff states by querying /api/v1/namespaces/{ns}/pods/{pod}/log and /api/v1/events resources.
Generates structured incident runbooks from AWS CloudWatch alarm configurations using the CloudWatch DescribeAlarms API and AWS Systems Manager documents. Links alarms to remediation procedures automatically.
Parses terraform plan JSON output to identify destructive changes, security group modifications, and IAM policy drift. Uses the Terraform Cloud API for workspace state comparison.
Validates Ansible playbooks using ansible-lint and the Ansible Galaxy API. Performs check-mode dry runs, validates role dependencies, and detects deprecated module usage across collections.
Scans AWS CloudWatch Logs using the CloudWatch Logs Insights API and CloudWatch Anomaly Detection API. Identifies unusual error patterns, latency spikes, and log volume anomalies across log groups.
Tests Prometheus alerting rules against historical metrics using promtool and the Prometheus HTTP API query_range endpoint. Validates PromQL expressions, simulates alert firing, and checks routing configurations.
Investigates CloudWatch metric anomalies using the AWS SDK CloudWatch.getMetricData and Logs.filterLogEvents APIs. Correlates metric spikes with log patterns and deployment events from CodeDeploy.
Diagnoses CrashLoopBackOff pods using kubectl and the Kubernetes API. Inspects container logs, exit codes, OOMKilled events, and liveness probe configurations to generate actionable remediation steps.
Debugs failed systemd services using journalctl, systemctl, and the systemd D-Bus API. Analyzes unit dependencies, ExecStart failures, resource limits, and generates fix recommendations.
Generates structured incident postmortems by aggregating data from PagerDuty incidents API, Slack channel history, and Grafana dashboard snapshots. Produces blameless postmortem documents following the Google SRE template format.
Detects infrastructure drift by running terraform plan -detailed-exitcode and parsing the JSON output via terraform show -json. Categorizes drift by resource type and generates targeted terraform apply plans for reconciliation.
Links Prometheus alerting rules to operational runbooks by parsing AlertManager configurations and PrometheusRule CRDs. Validates runbook_url annotations exist and are reachable, and generates stub runbooks for undocumented alerts.
Diagnoses Ansible playbook failures using ansible-playbook --check --diff mode, ansible-lint, and the Ansible callback plugin API. Parses task execution results and suggests fixes for common module errors in ansible.builtin and community collections.
